The 83rd annual holiday extravaganza will feature a 78-foot tall Norway Spruce from Gardiner, N.Y. It is approximately 80 years old and weighs approximately 10 tons.

Once again, “Green Is Universal,” NBCUniversal’s sustainability initiative in partnership with the Arbor Day Foundation, will kick off its annual tree-planting campaign during the “Christmas in Rockefeller Center” broadcast. This year, viewers can “GIF’t a Tree” to a national or state park or forest, by using #GIFtATree or visiting www.greenisuniversal.com to create and share an animated holiday tree GIF. Each action will contribute to the Arbor Day Foundation’s tree planting efforts, funded by a $25,000 donation from NBCUniversal.

Prior to the primetime telecast, an additional live hour of the special will be broadcast on select NBC stations (7-8 p.m. ET). Check local listings.
